We're dividing 81950899 by 485 
The aim is to understand the frequency of 485 in 81950899.

Going ahead to step 1:
8 divided by 485 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 485

Going ahead to step 2:
485 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (9) from the dividend, add it to 81, then carry on: 819 / 485

Step 3:
485 can be fit into 819 1 times, resulting in a remainder of 334.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 334 after subtracting 485 from 819.
Fetch the next digit (5) from the dividend, attach it to 334 and continue: 3345 / 485

On to step 4:
The number 485 fits into 3345 6 times, leaving a remainder of 435.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 2910 away from 3345, we end up with 435.
Include the next digit (0) from the dividend after 435, then repeat: 4350 / 485

Advancing to step 5:
The number 485 fits into 4350 8 times, leaving a remainder of 470.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
Deduct 3880 from 4350 and we're left with 470.
Fetch the next digit (8) from the dividend, attach it to 470 and continue: 4708 / 485

Going ahead to step 6:
485 can be fit into 4708 9 times, resulting in a remainder of 343.
Put 9 as the next digit of the answer. 
Result so far: 1689.0
Deduct 4365 from 4708 and we're left with 343.
Grab the next digit (9) from the dividend, add it to 343, then carry on: 3439 / 485

Advancing to step 7:
When dividing 3439 by 485, we get 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 16897.0
Subtract 3395 from 3439 to get 44.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 485

Moving on to step 8:
If we divide 449 by 485, we get 0 and a remainder of 449.
Record the quotient 0 as the next digit in the result. 
Result so far: 168970.0
The remainder is 449 after subtracting 0 from 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Moving on to step 9:
When dividing 4490 by 485, we get 9 with a remainder of 125.
Use 9 as the next digit of our solution. 
Result so far: 168970.9
If we subtract 4365 from 4490, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 10:
When dividing 1250 by 485, we get 2 with a remainder of 280.
The next digit of our result is 2. 
Result so far: 168970.92
If we subtract 970 from 1250, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
485 can be fit into 2800 5 times, resulting in a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 168970.925
Deduct 2425 from 2800 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 12:
When dividing 3750 by 485, we get 7 with a remainder of 355.
Put 7 as the next digit of the answer. 
Result so far: 168970.9257
If we subtract 3395 from 3750, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Going ahead to step 13:
When dividing 3550 by 485, we get 7 with a remainder of 155.
The next digit of our result is 7. 
Result so far: 168970.92577
Subtract 3395 from 3550 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The quotient of the division is 168970.92577, and the remainder is 0.000155.
